DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-3 , a guide wheel for an excavator that is easy to disassemble and assemble, comprising:

[0024] An installation frame 1 is provided, and sleeve rings 11 are rotatably installed on both side walls of the installation frame 1. A guide wheel 12 is provided between the two sleeve rings 11. Motors 14 are installed on both side outer walls of the installation frame 1 through connecting plates 13. The output shafts of the two motors 14 are fixedly connected to the two sleeve rings 11 respectively.

[0025] The mounting mechanism 2 is convenient for mounting and fixing the guide wheel 12, and includes hexagonal slots 21 provided at both ends of the axle of the guide wheel 12, each of which is slidably installed with a block 22, each of which is elastically connected to the inner wall of the hexagonal slot 21 through a first spring 23, and a hexagonal slot 24 is provided on one side wall of each sleeve ring 11 close to the block 22, and the hexagonal slot 24 cooperates with the block 22.

[0026] The clamping block 22 is hexagonal in shape, and two ends thereof cooperate with the hexagonal sliding groove 21 and the hexagonal clamping groove 24 respectively.

[0027] When the guide wheel 12 needs to be installed, the blocks 22 on both sides of the guide wheel 12 are pressed by the transmission block 31 to retract the blocks 22 into the hexagonal slot 21. Then, after the guide wheel 12 is placed in the installation frame 1, the transmission block 31 is released, and the two blocks 22 are automatically extended under the elastic force of the first spring 23 and enter the hexagonal slot 24. At this time, when the motor 14 drives the sleeve ring 11 to rotate, the guide wheel 12 can be driven to rotate synchronously to realize the conveying of the crawler.

[0028] The disassembly mechanism 3 facilitates the disassembly of the guide wheel 12, and includes a transmission block 31 installed on the two clamping blocks 22. Two moving rods 32 are slidably installed on the installation frame 1. The bottoms of the two moving rods 32 are respectively in contact with the two transmission blocks 31. The tops of the two moving rods 32 are both installed with a first hinge seat 34 through a mounting block 33. A lifting plate 36 is elastically connected to the top of the installation frame 1 through a second spring 35. Two second hinge seats 37 are provided below the lifting plate 36. Connecting rods 38 are provided between the two first hinge seats 34 and the two second hinge seats 37.

[0029] Among them, two limiting grooves 6 are opened on the installation frame 1, and the two moving rods 32 are slidably installed in the two limiting grooves 6 respectively. The moving rods 32 can be limited by the limiting grooves 6 so that the moving rods 32 can only move horizontally.

[0030] A pull ring may be provided above the lifting plate 36 , and the lifting plate 36 may be pulled to move upward by the pull ring.

[0031] In view of the problem that the steps of turning the bolts in the prior art are still relatively cumbersome, there is an urgent need for a guide wheel component that can be disassembled and assembled on the guide wheel more conveniently. The utility model sets a disassembly mechanism 3. When it is necessary to disassemble the guide wheel 12 for maintenance, it is only necessary to pull the lifting plate 36 upwards, and the two moving rods 32 can be brought close to each other under the action of the first hinge seat 34, the second hinge seat 37 and the connecting rod 38. The moving rod 32 pushes the transmission block 31 to abut against each other, so that the two transmission blocks 31 are brought close to each other, and the blocking block 22 is further moved out of the hexagonal blocking groove 24. The guide wheel 12 can be taken out of the installation frame 1 for maintenance. Compared with the existing method of turning the bolts, the method of pressing the transmission block 31 and pulling the lifting plate 36 can make the disassembly and assembly of the guide wheel 12 more convenient.

[0032] In addition, an arc-shaped push plate 5 is elastically connected to the bottom of the installation frame 1 through a third spring 4, and the arc-shaped push plate 5 is in contact with the axle of the guide wheel 12. After the blocking block 22 is moved out of the hexagonal slot 24, the elastic force of the third spring 4 can enable the arc-shaped push plate 5 to push the guide wheel 12 out of the installation frame 1, thereby automatically removing the guide wheel 12.

[0033] The functional principle of the utility model can be explained through the following operation modes:

[0034] When the guide wheel 12 needs to be installed, the blocks 22 on both sides of the guide wheel 12 are pressed by the transmission block 31 to retract the blocks 22 into the hexagonal slots 21. After the guide wheel 12 is placed in the installation frame 1, the transmission block 31 is released, so that the two blocks 22 are automatically extended under the elastic force of the first spring 23 and enter the hexagonal slots 24. At this time, when the motor 14 drives the sleeve ring 11 to rotate, the guide wheel 12 can be driven to rotate synchronously.

[0035] When it is necessary to disassemble the guide wheel 12 for maintenance, it is only necessary to pull the lifting plate 36 upwards, and the two moving rods 32 can be moved closer to each other under the action of the first hinge seat 34, the second hinge seat 37 and the connecting rod 38, and the moving rod 32 can push the transmission block 31 to abut against each other, so that the two transmission blocks 31 are moved closer to each other, and the card block 22 is further moved out of the hexagonal card slot 24. Subsequently, the elastic force of the third spring 4 can make the arc-shaped push plate 5 push the guide wheel 12 out of the installation frame 1, thereby automatically taking out the guide wheel 12, which is convenient for maintenance of the guide wheel.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
